Brimstone Dragons live in dry arid areas such as deserts where they feed mainly on sheep, goats and the occasional camel. Their favorite habitat is ideally situated close to the wastelands around active volcanoes. This is due to an important part of their diet—sulfur, which they obtain from deposits near volcanic gas vents. Instead of fire, these dragons use the sulfur they ingest to create a noxious gas which they store in their large throat pouches. When in danger, this gas is released in a large cloud. They also eat other mineral rich substances—including charcoal—and will drink the mineral rich (but slightly acidic) water commonly found in deserts and volcanic regions.

Dragons are highly-intelligent reptilian creatures that—from a human perspective, at least—appear to live forever. Many different varieties of dragon exist, each with their own unique qualities, habitats, and behavior. Adolescence in dragons is usually marked by the growth of a hatchling’s wings, although not all breeds of dragons grow wings and some breeds have other traits that indicate the beginning of maturation. In Galsreim, dragons and humans coexist peacefully.

Soto fuenga fire has a great immune system as he as almost never been sick in his life. Soto can eat and drink everything that is rotten and polluted. Even though he prefers to be around the wastelands near volcanoes he can also survive in very polluted areas. He is immune to the toxic filth and can eat from it without becoming sick, proving to be very resourceful when it is needed. He even voluntarily eat it as they don't find it disgusting but manly because it helps making their noxious gas more dangerous and toxic. Soto is a mechanical genius in his clan. Manly specialized in inventing boobytraps, as he creates a lot of them on a day near the borders of his clans territory to keep invaders out. Soto is a bit chubby and obsessed with cracking puns at every chance he sees. Soto is best friends with Vladimir lee, Pema lotus, Hades light, Rodney Rolls and Ross adjfd. These dragons are also close friends with each other.
